Imagine that you have two copies of a movie and two television sets. One copy is on Blu-ray and you pair that with a high-definition television — an HDTV. The other copy is on standard DVD, which you’ll watch on a standard-definition television. You synchronize both videos and watch the results.
The difference in image quality between the two sets should be obvious. The HDTV’s picture should look crisper and have colors far more vibrant than the standard counterpart. We’ve reached the peak of video quality — or have we?
When we talk about HDTVs, we’re really talking about image resolution. The picture on a television set is composed of millions of tiny dots of light called pixels. Standard-definition televisions have a resolution of 480. That means approximately 480 horizontal lines from the top of the screen to the bottom generate the images you see.
High-definition televisions pack more lines of pixels to create images. On the low end of the high-definition standard in the United States you have approximately 720 lines of pixels. On the high end, you have approximately 1,080 lines of pixels. Manufacturers are slowly phasing out the 720-line models in favor of the 1,080-line ones.
Using more pixels to create an image results in a smoother picture. Imagine you’re given a stack of green and brown squares of paper. You’re told you have to build a picture of a tree using the squares exactly as they are. If the squares of paper are large, your tree is going to look blocky with lots of jagged edges. But if you have smaller squares of paper, the tree will look smoother and more natural.
That’s what high-definition television does. It’s not just the number of pixels in the image — it’s the size of each individual pixel. As you pack more pixels into a screen, you have to make the pixels themselves smaller. In turn, the television will produce smoother images.
But is 1080 the best resolution possible? Could you buy a television set that packed even more pixels together? Would it make a difference? And would you be able to find programming that conformed to the higher resolution? Let’s find out.
When you walk into an electronics store for the first time and gaze at the enormous array of brightly lit screens facing you, it can be easy to forget that you need more than just the television set to enjoy high-definition programming. And beyond the necessities is a world of accessories that can enhance your viewing pleasure — possibly to the point where you’ll never want to leave the house again. If your new HDTV is to be the centerpiece of your entertainment center, den or man-cave, you may want to look at a few other products to create the best viewing experience.
While the following list will help you get the most out of your HDTV, there are a few items that didn’t make the cut that still merit some attention. Here are a few accessories that you may want to consider that are not on our list:
You may need to purchase special cables to get the most out of your HDTV. Component, HDMI and S-video cables can carry high-definition signals and provide sharper, more colorful images than composite cables. You’ll find these cables come in a wide variety of lengths and prices, with premium cables costing hundreds of dollars. Within the home-theater enthusiast community, there’s a spirited debate over whether high-end cables provide a noticeably improved experience.
Video game consoles with the ability to provide high-definition graphics are a good choice. Both the Xbox 360 and the Sony PlayStation 3 are capable of displaying games in high-definition resolution with the right television set and cables. The Nintendo Wii, while an innovative and popular console, doesn’t emphasize graphics the way Microsoft and Sony’s consoles do.
To fine-tune your HDTV settings and get the best performance, you may want to invest in a calibration system or DVD. These systems guide you as you set up your television so that your picture quality is at its peak.
If you have a flat-panel television, you may want to consider a wall mount. And because some people find visible cables unpleasant to look at, you may need to research solutions such as flat wire technology.
Now let’s get to the accessories that made our list. First is the most basic — and most important — consideration you’ll need to take into account. you can buy with payday loan
